Definitions

  • This invention relates to a temperature controller comprising a temperature-adjusting device and a heating device releasably attached to each other, in particular to a temperature controller comprising magnetic means for releasably attaching/detaching the temperature-adjusting device to/from the heating device.
  • FIG. 1 of the attached drawings shows a conventional temperature controller composed of a detachable temperature-adjusting device A as well as a heating device B.
  • the temperature-adjusting device A and the heating device B cooperatively realize temperature detection, electrical connection, and hence heating operation.
  • an elastic clamp A 3 is disposed in each conductive ring A 2 for clenching each conductive lever B 2 so as to fixedly connect the temperature-adjusting device A and the heating device B together.
  • the temperature-adjusting device and the heating device are combined by means of the elastic clamp arranged in each conductive ring.
  • the elastic clamp arranged in each conductive ring.
  • a primary object of this invention is to provide a temperature controller comprising a heating device and a temperature-adjusting device releasably mounted together by means of magnetic force so as to protect the devices from being damaged due to excessive insertion and separation forces.
  • a temperature controller in accordance with the invention comprises a temperature-adjusting device having a temperature-sensing portion and an output-power adjusting portion and a heating device having an electric heating element.
  • the output-power adjusting portion of the temperature-adjusting device forms two conductive rings and a plurality of magnet pieces located outside the conductive rings.
  • a plurality of magnet attractive pads is formed on a terminal face of the heating device at positions corresponding to the magnet pieces to induce magnetic attraction between the temperature-adjusting device and the heating device for enhancing the mounting force therebetween.
  • the force that secures the temperature-adjusting device and the heating device together is enhanced by the magnetic attraction induced by the magnet pieces and the corresponding magnet attractive pads.
  • the temperature controller is protected from being damaged by excessive insertion and separation force.
  • FIG. 1 is a perspective view of a conventional temperature controller
  • FIG. 2 is a perspective view of a temperature controller constructed in accordance with the present invention.
  • FIG. 3 is a front view of a temperature-adjusting device of the temperature controller of the present invention.
  • FIG. 4 is a front view of a heating device of the temperature controller of the present invention.
  • a temperature controller constructed in accordance with the present invention comprises a temperature-adjusting device 1 and a heating device 2 .
  • the temperature-adjusting device 1 comprises a temperature-sensing portion and an output-power adjusting portion.
  • a metallic temperature-sensing rod 11 and two conductive rings 12 are respectively formed on the temperature-sensing portion and the output-power adjusting portion.
  • a plurality of magnet pieces 13 is arranged on a common terminal face of the temperature-sensing portion and the output-power adjusting portion.
  • the conductive rings 12 are disposed respectively in holes (not labeled) defined in the terminal face on opposite sides of the temperature-sensing rod 11 .
  • the magnet pieces 13 are located respectively outside the conductive rings 12 .
  • a temperature-sensing hole 21 receives the temperature-sensing rod 11 therein to allow the temperature-sensing rod 11 to detect temperature of the heating device 2 .
  • the conductive pins 22 are formed by extending an electric heating element in the heating device 2 laterally nearby the temperature-sensing hole 21 for insertion into the respective conductive ring 12 for establishing electrical connection between and transmission of electrical power therethrough.
  • the magnet attractive pads 23 are disposed on respective outer sides of the conductive pins 22 at positions corresponding to that of the magnet pieces 13 to induce magnetic attraction between the heating device 2 and the temperature-adjusting device 1 .
  • the temperature-sensing rod 11 is first put into the temperature-sensing hole 21 , then the magnet pieces 13 are brought to approach the magnet attractive pads 23 in a face to face manner to finally contact with each other as soon as the conductive levers 22 are plugged into the conductive rings 12 .
  • a user only has to grasp the temperature controller at its two ends and pull it laterally and outwardly with hands so that the magnet pieces 13 and the magnet attractive pads 23 , also the conductive levers 22 and the conductive rings 12 are separated from each other to have the temperature-adjusting device 1 and the heating device 2 detached from each other.
